8 INSTALLATION

The Style 3 SBGL light units are shipped complete, including the lamp(s), and are ready for installation as received. Installation of a light unit is to be done with primary POWER OFF and SECURED. At each SBGL light location, install a steel Size B, 12 inch deep minimum, L-868 Light Base per FAA AC 150/5340-4 (latest revision). For SBGL fixtures, install the light base with two opposite bolt holes parallel to the runway centerline. Place the properly sized isolation transformer(s) in the light base and make necessary primary power connections using L-823 connectors. The SBGL light unit requires either two 100 watt, 6.6A secondary transformers for the two lead version, or one 100 watt, 6.6A secondary transformer for the single lead version. Note that the two lead fixtures require two separate circuits for operation, so that the two circuits cannot be energized at the same time, see FAA AC 150/5340-28 for more information. Verify that the mounting flange on the light base is clean and the o-ring (optional on deep cans) is coated with Dow Corning FS 1292 grease and is in place on the light base. Connect the plug(s) from the light unit to the secondary (ies) of the previously installed isolation transformer(s). Installation tool, Crouse-Hinds P/N 19999, will ease in the installation and removal of the light unit (See Figure 6). The threaded eyebolts on the lifting tool screw into threaded holes in the light fixture. Lower the light unit straight down onto the base. The light fixture is subject to optical misalignment or mechanical damage if not seated properly. Verify the light beam(s)/color(s) are properly orientated for the individual location. Secure the light fixture to the base with six 3/8-16 UNC x 7/8 lg. stn. Stl. bolts and lock washers and tighten to 225 -0 +10 in-lbs. (18 ft-lbs.). It is recommended that Loctite 242 be used on the mounting bolts to prevent loosening due to vibration. It is highly recommended for fixtures subjected to repeated aircraft impacts and roll-overs.

9 MAINTENANCE

The preferred method of maintaining these lights is to periodically and systematically replace the Optical Assembly and return it to the maintenance shop for renovation. As an alternative, the Optical Assembly can be serviced in the field. However, it is recommended that field servicing be limited to cleaning the lens as described in section 9.1 and to lamp replacements as described in section 9.2.

9.1 Cleaning Lenses

With a compressed air blast or suitable brushes, remove all accumulated debris from the light channel. Clean the outer surface of the prism with a detergent solution. If the lens is coated with a substance impervious to the detergent, a suitable solvent should be sparingly applied with a wad of cotton or a patch of cloth on the end of a wood splint. After the solvent has acted the remaining solvent and softened coating should be removed with a clean piece of cotton or cloth. Care should be taken to avoid excessive contact between the solvent and the lens seal. Remove all remaining solvent from lens and seal. A gentle air blast may be used.

9.3 Gasket Replacement

Every time the Optical Assembly is opened the gasket must be closely examined and replaced if necessary. Any gasket that is stretched, torn, has a permanent set or some other defect, which would prevent it from forming a watertight seal, must be replaced with a new gasket. Remove the old gasket from the groove in the inner cover. Carefully clean the flange mating surfaces and the inner cover groove. This can be done by carefully scraping. Take care not to damage the mating surface and the bottom and sides of the groove. Coat the gasket (P/N 21140) with a thin layer of Dow Corning FS 1292 Lubricating grease. Position the new gasket in the center of the groove and press it into place. The groove is designed to be wider than the gasket, this provides room for displacement of the gasket when compressed between the housing load mating surfaces. The grease will hold the gasket in place while the inner cover is positioned on the light housing. Torque the inner cover screws to 30 in-lbs. Perform a pressure test as described in paragraph 9.10. Clean the mounting flange area of the support ring. Place the Optical Assembly into the support ring. Install new stainless steel, split-ring lock washers.

9.6 Pressure Test

A light fixture should be subjected to a 20-psi air pressure test to verify that it is waterproof whenever it has been opened or components have been replaced. A tire valve style pressure fitting is located on the bottom of the inner cover. Pressurize the fixture to 20-psi then place it in a tub of water or use a soap solution to locate escaping air bubbles. Carefully inspect the areas around the lens, inner cover seal, and feed-thru adapter for leaks. Relieve the internal air pressure before installing the fixture or attempting to repair a leak.

WARNING:

WARNING

Do not exceed 20 psi when pressure testing the fixture. Serious injury and/or permanent damage to the fixture may result if a higher air pressure is used. Once the pressure test is complete be sure to relieve the air pressure.

9.7 Cleanliness and Workmanship

Service life depends upon the entire assembly being waterproof. All surfaces must be clean, dry and free of all foreign matter if the light fixture is to operate for extended periods without requiring maintenance.

9.8 Maintenance Program

In order to insure maximum light fixture life, the installed units should be subject to a maintenance program in accordance with the following: A daily operation check should be made of the lighting fixture. The lights should be energized and visually inspected. If any lamps are out, the location of the fixture should be recorded and the lamps replaced at a time when the circuit is de-energized. (See Section 9.2)

9.8.1 Regular cleaning is necessary in order to insure that inset lighting fixtures operate at maximum

efficiency. The lens and channel in front of the lens should be cleaned periodically with a soft cloth and solvent. The weather and the location of the fixtures will dictate the regularity and type of cleaning.

9.8.2 Snowplow operators should exercise extra care not to strike the light fixtures with snowplow

blades. After snowplow removal operations, inspect all light fixtures to locate and replace if necessary, any damaged Light Assemblies. Passes over the light rows should be made with a power broom only if practical. Whenever snowplows must traverse in-pavement light fixtures, they should be traveling at less than 5 mph or have the blades lifted clear of the fixtures. Recommended snow removal techniques are described in AC 150/5200-23.

9.8.3 The light is designed to exclude both ground and surface water from entering. If the lights are not

properly maintained (i.e., bolts tightened and seals in good condition) water may enter the fixture. To prevent this from occurring, it is recommended that each fixture be inspected for the presence

of water at least once a month. More frequent inspection is desirable during and following rainy seasons

9.8.4 Optical Assembly and support ring hold-down bolts should be checked for proper torque (225 +5,

-0 in-lbs.) at least once every three months or whenever a fixture is serviced regardless of the season. Light fixtures in and around high speed exit areas are especially prone to vibration damage if the mounting bolts are not properly torqued. It is recommended that Loctite 242 be used on mounting bolts to prevent loosening due to vibration. The mounting surface of the light base must be clean and free of foreign matter when checking mounting bolts.

9.8.5 If any fixture contains water, the water should be removed and the entire fixture cleaned and

dried. Perform a pressure test per paragraph 9.10 to locate the source of the leak. Replace the bottom cover gasket, or optical housing o-ring, See Sections 9.3, 9.4 and 9.5.
